Background technology
The driving system of motor vehicle driven by mixed power will comprise that traditional propulsion system of combustion engine and step type automatic transmission with hydraulic torque converter combines with energy storage system, and the fuel economy with the driving system that improves conventional truck makes it to surpass conventional truck.The various technology that are used to regenerate and store the kinetic energy of vehicle comprise: power driven system comprises electrical motor and storage battery; Hydraulic efficiency pressure system stores energy in the hydraulic fluid tank (pressurized hydraulic tank) of pressurization; Fly wheel system stores energy in the flywheel or dish of rotation.
The main difficult problem that fly wheel system exists is: needs are powerful and to wheel flywheel torque is provided reposefully.A kind of like this method has been proposed: confirm wheel torque through measuring as the wheel slip of the input that the flywheel torque that is delivered to wheel is controlled.Very strict and may change owing to this measurement along with environmental conditions, cause having point-device Transmission Ratio Control, so possibly be difficult to carry out this measurement.Especially under the situation of low load, in vehicle, be difficult to wheel slip is measured, and wheel slip has high gain.Little error in this measurement possibly cause big control disturbance.
Summary of the invention
A kind of method that is used for the driving system of controlling machine motor vehicle, said method comprises: the flywheel torque of confirming expectation; With reference to the definite clutch torque capacity moment of torsion of expecting of the flywheel torque of expectation, through power-transfer clutch transfer torque between flywheel and wheel of vehicle; Operated clutch is to produce the clutch torque capacity of expectation; Confirm the error of trackslipping on the power-transfer clutch; Will be at the gear ratio change of the toric transmission in the driving path between power-transfer clutch and the said wheel speed ratio to the error that reduces to trackslip.
The present invention also imagines a kind of system that is used for transmitting the power of driving system, and said system comprises: flywheel; Wheel of vehicle; Power-transfer clutch is through power-transfer clutch transfer torque between flywheel and said wheel; Toric transmission is in the driving path between power-transfer clutch and said wheel; Final drive gear is in series arranged with said toric transmission in the driving path between said toric transmission and said wheel.
Under the situation that vehicle quickens, flywheel torque provides the positive moment of torsion of increase, to replenish the driving system moment of torsion that is delivered to wheel.Under the situation of car retardation, flywheel provides negative torque to wheel, thereby replaces the friction braking moment of torsion of wheel, so that the kinetic energy of vehicle is recovered and stores, and propelled vehicles after being used for, rather than waste through the friction on the brake lining.
The output torque of control flywheel so that accurate moment of torsion to be provided to wheel, thereby satisfies the wheel torque of chaufeur needs all the time.The torque demand of chaufeur is the combination that the output of basic driving system adds the moment of torsion output of flywheel.

Description of drawings
Through the description that reference is carried out below in conjunction with accompanying drawing, the present invention is easy to understand more, in the accompanying drawing:
Fig. 1 is the scheme drawing of flywheel-type hybrid power transmission system;
Fig. 2 is fixed speed ratio wheel word and the scheme drawing of toric transmission that illustrates in the driving system;
Fig. 3 is the block diagram of method of moment of torsion that is used for the driving system of control chart 1 and Fig. 2.
The specific embodiment
Now, with reference to accompanying drawing, Fig. 1 schematically shows the hybrid power transmission system 10 that is used for power actuated vehicle. Front vehicle wheel 12 and 13 can be connected to the propulsion source 14 such as combustion engine (ICE) drivingly through change-speed box 16 (preferably, how fast step type change-speed box) and preceding box of tricks 18.Rear wheel 20 and 21 can be connected to the hybrid power source such as flywheel assembly 22 drivingly through change-speed box 24 (preferably, toric transmission (CVT)), axle drive shaft 26 and back box of tricks 28.CVT 24 generation input speeds are stepless to output speed, the speed ratio of continuous variable.Tape drive mechanism and traction drive mechanism are used for 24 transferring power through CVT.
In this hybrid power transmission system 10, the wheel braking energy is mechanically regenerated and is stored in the flywheel 22.The speed ratio of CVT 24 changes in the opereating specification of CVT, to allow rotating energy to be stored in the flywheel 22 or to discharge and be delivered to wheel 20 and 21 from flywheel.
Fig. 2 shows the example for the possible speed ratio of given application.Flywheel assembly 22 comprises flywheel 29; Flywheel 29 is connected to the sun gear 30 of simple planetary group 32, compound planet gear 32 also comprise be fixed and non-rotary Ring gear 34, tooth rest 36, be supported on the tooth rest and with sun gear and Ring gear ingear planet pinion gear 36.Preferably, the speed ratio that is produced by gear cluster 32 is about 5.07.Compound planet gear 32 is called as gear 3.
Tooth rest 36 is connected to and miniature gears 40 gears in meshs 38.Preferably, gear 38 rotates than about 2.6 times soon of miniature gearss 40.Miniature gears 40 jointly is called gear 2 with gear 38.Flywheel torque is the moment of torsion that on axle 41, transmits.
Belt wheel 42 can be connected through rotating band 46 with 44 drivingly, and the radial position of rotating band 46 on belt wheel changes.Change in the preferable range of CVT speed ratio between 2.54 and 0.42.Power-transfer clutch 48 can connect belt wheel 42 and miniature gears 40 drivingly.
Belt wheel 44 is connected to and miniature gears 52 gears in meshs 50.Preferably, gear 50 rotates than miniature gears 52 fast approximately 1.59.6 doubly.Miniature gears 52 jointly is called gear 1 with gear 50.
Comprise that the axle drive shaft 26 of two constant speed (CV) universal-joint 54 and 56 can be connected to the Ring gear 58 of back box of tricks 28 drivingly through miniature gears 60.Back box of tricks 28 produces about 3.58 final transmitting ratio.
Clutch torque capacity is the rangeability that is delivered to the moment of torsion of power-transfer clutch under the arbitrary operating conditions in the operating conditions (that is, trackslip, partial engagement or full engagement) at power-transfer clutch.
Suppose that the pressure on the friction surface of power-transfer clutch is even, then
Torque＝N surfaces*F clutch*mu*(D outer^3-D inner^3)/3*(D outer^2-D inner^2) (1)
Wherein, Torque is a clutch torque capacity, F ClutchBe the amplitude of power that normally is applied to each friction surface of power-transfer clutch, mu is a friction coefficient, and N is the quantity of clutch friction surface, D OuterBe the overall diameter of friction surface, D InnerIt is the interior diameter of friction surface.
Making the power on the servo piston of clutch operating is the function that is applied to the hydraulic pressure of piston,
F piston＝Pressure*Pi*(D outer?piston^2-D inner?piston^2)/4 (2)
Wherein, F PistonBe the power on the servo piston, D Outer pistonBe the overall diameter of piston face, D Inner pistonIt is the interior diameter of piston face.Therefore, the torque capacity of power-transfer clutch 48 is functions of the pressure of the variation on the servo piston of action.The fine pressure that pressure (Pressure) refers on servo is strong, that is, actual pressure deducts and overcomes the required pressure of servo pull back spring.
According to Fig. 2, the output torque that is delivered to wheel 20 and 21 is the function of clutch moment of torque,
T Output=T Clutch* CVT speed ratio * gear 1 speed ratio * FD speed ratio (3)
Can set up the relation of clutch pressure-clutch moment of torque based on the geom of piston and power-transfer clutch.In order to control flywheel torque, control clutch pressure provides the output torque of expectation.
Except output torque, go back trackslipping on the control clutch 48.Trackslip through control clutch, flywheel 29 perhaps releases energy harvest energy.The direction of energy Flow depends on the direction of slipping of clutch.When gear 2 sideway swivels of power-transfer clutch 28 must be faster than the CVT side of power-transfer clutch, positive clutch occur and trackslip.Along with the speed reduction of flywheel, just trackslipping causing energy to be delivered to wheel 20 and 21 from flywheel 29.When the CVT of power-transfer clutch 28 sideway swivel must be faster than gear 2 sides of power-transfer clutch, produce negative slipping of clutch.Along with the speed increase of flywheel, negative trackslipping with causing rotating energy to be stored in the flywheel 29.
Fig. 3 shows the block diagram of the step of control method, and this control method has been cancelled needs to use wheel slip to be controlled to the flywheel torque of wheel as input variable.On the contrary, regulate the CVT speed ratio, to keep slipping of clutch through the closed loop control of slipping of clutch.
Chaufeur demand 64 is as reference, and to confirm the flywheel output torque 72 of expectation from torque distribution variable 70, chaufeur demand 64 is represented by the degree of displacement of acceleration pedal 66 or the degree of displacement of engine air throttle 68.
At step 74 place; The flywheel output torque 72 of expectation is divided by the speed ratio and the CVT speed ratio of the drivetrain components in the power path between wheel and the CVT belt wheel 44; That is, divided by (the gear 1 speed ratio * FD speed ratio) of product, with the torque capacity 78 of the expectation of confirming power-transfer clutch 48.
At step 80 place, the torque capacity 78 of the expectation of power-transfer clutch 48 to confirm the amplitude of pressure 82, utilizes this pressure 82 to make the clutch torque capacity 78 of clutch operating and generation expectation divided by the gain (clutch moment of torque in every pressure unit) of power-transfer clutch.
Be stored in signal that function 84 in the electronic memory produces representative and the slipping of clutch 86 of the cooresponding expectation of current operating conditions as output.Preferably, the slipping of clutch 86 of expectation has low amplitude, and this is because the expression of trackslipping makes the degradation of energy of the friction surface heating of power-transfer clutch 48.
Confirm the difference between perhaps actual slipping of clutch of measuring 88 and the slipping of clutch of expecting 86 at summing junction 90 places; The output of summing junction 90 is the errors 92 of trackslipping; The error of trackslipping 92 multiply by the gain 94 (the CVT speed ratio in every slipping of clutch unit) of CVT 24, to confirm CVT speed ratio error 96.
Closed loop controller 98 (preferably, the PID controller) receives CVT speed ratio error 96 as input and the 100 conduct outputs of generation command signal, and command signal 100 expressions will make the error 90 minimized CVT ratio change of trackslipping.In response to command signal 100, at rotating band 46 and the belt wheel 42 of CVT 24 and 44 joint, radius changes, thereby through specifying the amplitude (magnitude of commanded change) that changes in the CVT gear ratio change CVT speed ratio 100.
According to the regulation of patent statute, preferred embodiment has been described.Yet, should be noted that, except illustrating particularly and describing, can also implement alternate embodiment.
